$pecification forming part of Letters Patent No. 115,802, dated June 13, 1871 antedated May 29, 1871.

To (all whom it may concern:

I, FRANCIS ALGER, of Boston, in the county of Suffolk and State of Massachusetts, have invented a certain new and useful Improvement in SteamGarriages for Common Roads, of which the following is a complete specification Nat-are and Objects of the Invention.

The nature of my invention consists in combining certain improved devices to a steamcarriage to facilitate the management and running of the same. The peculiar character of these devices can only he understood by reference to the drawing and specification.

Description of the Drawing.

Figure l is a perspective view of the carriage. Fig. 2is a vertical section of the same. Fig. 3 is a plan, shown] g the under side of the same.

General Description.

a represents the boiler, which is hung upon a suitable frame, and near the forward axle, as shown in the drawing. This boiler is a tube, A, but is not a baseburner. C is a fuelhopper, located as shown, and is provided with a sliding bottom, C operated by the handle 0 Surplus fuel my be stored in the fuel-box F. The ash-pit D has an open grill in front and a door, E,- in the rear. This door is closed and opened by the handle E, Fig. 2. The forward axle is pivoted at the center, so that by tnrnin g it the carriage may be directedat will. This is eii'ected by the following device: h h, Fig. 3, is a rope or chain attached to the axle, as shown, and passed around the grooved wheel E. This grooved wheel H is made to handle, having a t0gg1B-j0i11t,'.K and serves connection with the double pawl L which is affixed tot-he wheel, that the axle can revol vc in one direction only without causing the wheel to revolve also. As the pawl is set in Fig. 2, the revolving of the axle would cause the wheel to go forward; but if the spring L be placed upon the other side of the pawl, then the carriage may be made to go backward. The object of the pawl L and disk L is to allow one wheel to go faster than the other, as it has a tendency to when the carriage is being turned. Thus, if the carriageis going forward, the wheel on the inner side of the circle would be driven by the axle and carry the carriage along; but the wheel on the outside revolves faster than the axle. Thus it would be free to do, as the pawl L would be carried backward over the notches in the disk L .By this arran gement the carriage may be turned easily.

What I claim as my invention is-- 1. The steering-handle K when provided with a toggle-joint, K", in combination with endless screw K gear K, wheel H, and steering-ropes h h, substantially as described, and for the purpose set forth.

2. The combination of the double pawl L the disk L and axle L, operaiin g substantially as described, and for the purpose set forth.
